In the Dong'an City Police Station, Li Zhitong, who thought he could rest for a while, had already snuggled up in a chair and was asleep for less than five minutes before he was woken up by Lao Chen, who had just returned from the team. Pen "Fun" Pavilion www.biquge.info

Li Zhitong recovered his spirits quickly, and he immediately came to his senses after knowing that there was a case.

"What's wrong?" Li Zhitong didn't look sleepy at all, which made Lao Chen feel very surprised.

"Here we go again." Lao Chen said nervously.

"Where?"

"It's the square where we suspected Li Jiayu before, there was a group of retired old people playing chess in the pavilion, there were two people playing chess at that time, and five people were watching, everything was fine at that time, but suddenly, an old man who was watching fell down, and after forensic examination, the deceased was stabbed in the back of the neck by a poisonous needle and died."

"Does it have anything to do with the ruling year Tai Sui?"

"A note was found in the pocket of the deceased with only four words written on it."

"Ruling too old?"

"No, do harm to the people!"

"What did the deceased do before he retired?"

"It was the leader of a factory, and a few years ago he was investigated in connection with a bribery case, but he was not arrested because of his age."

"Over eighty?"

"Yes, eighty-three."

"Is this the case?"

"Of course not, there is another one that also happened in the square, and also this morning, it was a group of elderly people who were whipping in the square, and the cause of death was also a poisonous needle in the back of the neck, and the public opinion of these two cases expanded rapidly, and now the Internet has exploded, and the superiors ordered us to solve the case before dark."

"Let's go and see it!"

At this time, the scene of the crime has been cordoned off, but there are still many onlookers.

"Have you found the poison needle?" Li Zhitong asked.

"It's all on the back of the deceased's neck." Lao Chen said.

"That would rule out the idea that the murderer was close to the deceased, right?"

"Yes, it should be the murderer who used some method to shoot the poison needle, but it will be difficult to solve the case in this way."

"Did the old man who threw the whip have a conflict with the others?"

"Through the investigation, the old men who threw the whip exercised in the square from time to time every day, and the nearby residents had a conflict with them, because the noise of the whip was too loud, but in the end, civil mediation was useless, and the old man still threw the whip as usual."

"Then the suspect should be easy to investigate, right? Were there any people who had a conflict with the old man at the time? ”

"Yes, and the three suspects were locked, but no poison needle was found on the three suspects, and the police who handled the case have investigated all the possibilities, and in the end, there was really no way, so they reported the case to our group."

"I'll meet those three suspects." Li Zhitong said.

Three suspects are waiting for interrogation at the scene of the crime, the first is a high school student who has just come of age and is preparing for the college entrance examination next year, but the old man who throws the whip makes noise from time to time every day, which makes him deeply troubled.

After the previous police investigation, high school students in the scene of the crime near the small pavilion review, is comfortable, the old people suddenly picked up the whip, someone nearby saw the high school student's behavior is a little strange, originally high school students are angry is also normal, but someone saw the high school student holding something to the old man who shook the whip, after the investigation, the high school student said that it was a water-based pen that was about to run out, and the old man was just angry in his heart could not be vented, so he made such a move by inertia, The police did find the water-based pen not far from the high school students.

The second person is a newly married guy nearby, the house has just been bought, but there is a lot of noise in the house near the square every day, and he is the first to conflict with the whip throwing brigade, but in the end, the newlywed guy still can't resist the old people playing scoundrels, so he can only swallow his anger.

At that time, the newlywed guy was walking his dog by the fountain near the scene of the crime, and no one noticed that the newlywed guy had done anything strange.

The third person was a homeless man resting on a bench near the scene of the crime, about 40 years old, with a very fierce face, who had a conflict with the old people, because it affected his sleep, and he also beat several elderly people at that time, and was finally administratively detained for half a month. Since then, the homeless man has never had a conflict with the old people, and this time the homeless man was also woken up by the old man who threw the whip, but the homeless man soon moved to a farther place to rest.

"These are the three suspects?" Li Zhitong said.

"That's right, let's help investigate!" Lao Chen said with a sleepy face.

"The homeless can basically be ruled out, because the kind of people at the bottom of the society are the people who are hated by the ruling Tai Sui, and if it is to manipulate the homeless to commit crimes, I think it is a little unlikely."

"I think so too, but at least we should look into it."

"Isn't that easy? Figuring out what kind of profession the newlywed guy walked the dog was in will be able to figure it out. ”

"Do you suspect that the newlywed guy committed the crime?"

"You can judge by the elimination method that the homeless man is the kind of person who is tired of being too old, although high school students have the possibility of committing crimes, but I think the technical work of shooting a poison needle should be related to the murderer's daily work, and now high school students are so busy that they don't have time to practice this technique."

Lao Chen quickly brought the newlywed guy to Li Zhitong, Li Zhitong broke the guy's hand, and as expected, the guy's palm had a lot of calluses, which was very inconsistent with the guy's age.

"Hard work?"

"Renovation worker!"

Li Zhitong rummaged through the pockets of the guy's clothes, but there was nothing, and the guy's face also showed a very relaxed look.

"Ask someone to go to the fountain pool to look for the murder weapon, it should be a metal tool, and it can be easily found." Li Zhitong said.

After the young man heard Li Zhitong's words, his face was frightened, and after a while, the police handling the case found something similar to a homemade small slingshot in the fountain pool.

"Who instructed you to commit the crime?" Li Zhitong asked.

"I ...... I got this murder weapon from a website, I originally signed up with the attitude of trying it out, and I was also panicked when I was selected, but if I don't follow the mission of the website, my family will be retaliated by them, and I don't know why those people know the details of my family, and I have no choice but to follow the mission of the website. ”

"What nonsense are you talking about? Say it well. ”

"Recently, there is a popular website on the Internet that can help people take revenge, as long as they talk about their troubles, the website can provide a set of killing methods to customers, and can also send customers tools for killing. I was very panicked when I received the murder device, and I was planning to throw it away, but I suddenly received a phone call on the other end of the phone, which made it very clear about my parents' and wife's work units and living habits, and I understood at that time that if I did not continue with the murder plan, my family would be in danger. ”
